Currently, Own-AI has only a light theme. I request a dark mode option to improve the user experience. Dark mode reduces eye strain, especially in low-light environments, and also helps save battery life on OLED displays. This feature would allow users to switch between light and dark themes based on preference.

Proposed Implementation:

• Add a toggle button to the user interface to switch between light and dark modes.
• Maintain proper color contrast and accessibility compliance to support visually impaired users.
• If possible, follow system preferences (light/dark) on supported browsers and devices.
